Mesmerizing red sand dunes jigsaw puzzle

A few clues to get started

Explore travel, landscape. Look for these features as you bring the picture together:

• Use a visible ridgeline or cliff edge to divide sky from land. Match the angle of that line, then work into rock, snow, or shadow only where those details appear.
• Use the boundary between light and shadow to organize sandy areas. Follow any visible dune or rock outline before filling broad regions of similar color.
